Gx Tron is one of the oldest archetypes in Modern’s history. It started out as a “12-Post” deck, but soon evolved to a different variant after Cloudpost was banned for being too consistently powerful. For a long time RG Tron was the de facto consensus build, splashing red mainly for removal purposes. Later versions have turned to black and white for disruption and sideboard flexibility in cards such as Collective Brutality and Rest in Peace.

Gx Tron is one of the true staples of the format, splitting most of its time between Tier 1 or Tier 2. It tends to crush fair decks while struggling against fast combo, which means its stock can shift dramatically depending on metagame.
